Technical Field

[0001] This utility model relates to the field of mechanical parts processing technology, specifically to a powder forming electro-hydraulic servo press with cleaning function. Background Technology

[0002] The powder forming electro-hydraulic servo press is a forming device that uses fine metal or ceramic powders as raw materials and is precisely controlled by an electro-hydraulic servo system. It is widely used in fields such as cemented carbide, structural ceramics, powder metallurgy, metal powders, cutting tools, and mechanical parts. It is particularly suitable for producing powder products with complex shapes, high dimensional accuracy, and high performance requirements. The working principle of the powder forming electro-hydraulic servo press can be summarized in the following steps:

[0003] 1. Fill the mold with the precisely proportioned powder material;

[0004] 2. The electro-hydraulic servo system presses the powder with precise force according to a preset program;

[0005] 3. Maintain a certain pressure to ensure uniform molding density.

[0006] 4. Release the pressure and remove the molded part from the mold;

[0007] Existing electro-hydraulic servo presses for powder forming do not have an automatic powder cleaning function. During the processing, a large amount of powder will accumulate on the machine body. To clean the powder, the electro-hydraulic servo press for powder forming can only be stopped. Stopping the electro-hydraulic servo press for powder forming not only reduces processing efficiency, but also makes powder cleaning time-consuming and labor-intensive, increasing the workload of workers.

[0024] The powder collection mechanism includes a dust collection box 9, a filter screen 10, and a fan 11. The dust collection box 9 has an air inlet and an air outlet. The filter screen 10 is vertically installed inside the dust collection box 9, with the air inlet and air outlet located on both sides of the filter screen 10. The air inlet is connected to the dust collection chamber 7 through a pipe. The fan 11 is installed on the top of the dust collection box 9 and is connected to the air outlet through a pipe. A V-shaped groove 12 is provided on the bottom of the dust collection box 9 facing the air inlet. A drain pipe 13 is provided at the bottom of the V-shaped groove 12. A powder collection bottle 14 is threaded to the lower outer wall of the drain pipe 13. A plate valve 15 is provided on the drain pipe 13. An electric telescopic rod 16 is provided inside the dust collection box 9 facing the air outlet. A push block 17 is provided on one side of the electric telescopic rod 16 and is attached to the filter screen 10.

[0025] In this embodiment: Powder supply 1 supplies powder to the forming and molding mechanism. After powder supply, the electric hydraulic telescopic cylinder 2 is activated to press and mold the powder. By setting a limiting sleeve 4, the leaked powder can only accumulate in the limiting sleeve 4. By activating the fan 11, suction is generated in the dust suction hole 8 and the dust suction chamber 7, which easily sucks the leaked powder into the dust collection box 9. The powder is then filtered onto the filter screen 10, and the airflow is discharged from the fan 11 through the filter screen 10, which facilitates automatic and rapid cleaning of the powder forming electro-hydraulic servo press. When too much powder is collected inside the filter box, the fan 11 is turned off, the electric telescopic rod 16 is activated, and the push block 17 reciprocates. Tapping the edge of the filter screen 10 makes it easier for the metal powder on the filter screen 10 to fall downwards, avoiding clogging of the filter screen 10. The fallen powder collects in the V-groove 12. Opening the plate valve 15 on the drain pipe 13 allows the drain pipe 13 to act as a guide, making it easy to collect the powder into the powder collection bottle 14. The port of the powder collection bottle 14 is threadedly connected to the drain pipe 13. Rotating the powder collection bottle 14 makes it easy to clean the powder collected in the powder collection bottle 14. This makes the powder easy to clean and collect, avoiding waste and saving costs. It also eliminates the need for manual cleaning, improving the convenience of the device's processing. Furthermore, the powder forming electro-hydraulic servo press does not need to be stopped, and the powder can be cleaned and collected, improving processing efficiency.

[0026] The dust collection box 9 is fixedly connected to the limiting sleeve 4 via a connecting rod.

[0027] As a technical optimization of this utility model, the forming and molding mechanism and the powder supply 1 are both located below the crossbeam 6; the forming and molding mechanism includes a forming cavity 18 embedded in the top of the load-bearing base 3 and a forming pressure seat 19 set above the forming cavity 18; the electric hydraulic telescopic cylinder 2 is set on the top of the crossbeam 6, and the output end of the electric hydraulic telescopic cylinder 2 is set on the top of the forming pressure seat 19; a telescopic device 20 is set behind the limiting sleeve 4, and the output end of the telescopic device 20 is set on the powder supply 1. The telescopic device 20 is a pneumatic telescopic rod or a hydraulic telescopic rod.

[0028] A conveyor belt 21 is provided on the side of the load-bearing base 3 facing the opening of the limiting sleeve 4, and the upper end face of the conveyor belt 21 is in the same plane as the top of the load-bearing base 3; a baffle 22 is provided on the side of the conveyor belt 21 away from the load-bearing base 3.

[0029] In this embodiment: The telescopic device 20 is activated, enabling the powder supply 1 to move back and forth, facilitating its movement onto the molding cavity 18 for powder supply (the powder supply 1 is prior art, and its specific structure is not shown in detail in the figure). After powder supply, the powder supply 1 is reset via the telescopic device 20. The electric hydraulic telescopic cylinder 2 is activated, causing the molding pressure seat 19 to move downwards, facilitating pressure molding of the powder within the molding cavity 18. After molding, the electric hydraulic telescopic cylinder 2 drives the molding pressure seat 19 downwards, and the pushing mechanism at the bottom of the molding cavity 18 pushes the molded film... The pre-formed parts processed in cavity 18 are automatically pushed to the top of the forming cavity 18 by the pushing mechanism, which is existing technology; when the powder supply 1 supplies powder, it moves forward in the direction of the conveyor belt 21, which makes it easy to push the pressed parts onto the conveyor belt 21, and the conveyor belt 21 makes it easy to transport the parts to the next process for sorting, realizing the function of automatic conveying; after the powder supply 1 pushes, it moves again to the forming cavity 18 to supply powder into the forming cavity 18; the baffle 22 restricts the powder forming parts pushed onto the conveyor belt 21 to prevent the powder forming parts from falling.

[0030] Working principle: Powder supply 1 supplies powder to the forming and molding mechanism. After powder supply, the electric hydraulic telescopic cylinder 2 is activated to press and shape the powder. By setting a limit sleeve 4, leaked powder can only accumulate inside the limit sleeve 4. By activating the fan 11, suction is generated in the dust suction hole 8 and dust suction chamber 7, which easily sucks the leaked powder into the dust collection box 9. The powder is then filtered onto the filter screen 10, and the airflow passes through the filter screen 10 and is discharged from the fan 11, facilitating automatic and rapid cleaning of the powder forming electro-hydraulic servo press. The powder collected inside the filter box... When there is too much powder, turn off the fan 11, start the electric telescopic rod 16, and push the block 17 to reciprocate and knock the edge of the filter screen plate 10, so that the metal powder on the filter screen plate 10 can fall downwards, avoiding clogging of the filter screen plate 10. The fallen powder will collect in the V-shaped groove 12. Open the plate valve 15 on the drain pipe 13. The drain pipe 13 plays a guiding role, making it easy to collect the powder into the powder collection bottle 14. The port of the powder collection bottle 14 is threaded to the outer wall of the drain pipe 13. Rotate the powder collection bottle 14 to separate the powder collection bottle 14 from the drain pipe 13, making it easy to clean the powder collected inside the powder collection bottle 14.

[0031] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
